SPECIFICATION forming' part of Letters Patent No. 732,926, dated July 7, 1903.

Application filed OctoberlZG, 1901. Serial No. 80,068. (No model.)

` To all whom itlma/y concern.'

Be it known that I, REvERDY CLEMENT` DE LA HUNT, a citizen of the United States, re-

siding at Cedar Rapids, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Deodorizing De vices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

My invention relates to water-closets, and has for its object to provide certain new and useful improvements in reference to the same.

A further and more specific objectof my invention is to provide a simple and effective means for carrying off the stench from watercloset bowls.

A further object of my invention is to provide a means for carrying off the stench from water-closet bowls which may be attached and used to existing bowls and connections.

A further object of my invention is to provide a device for the above purposes which is simple in its operation, cheap to manufac-` ture, and, above all, practical and efficient.

Vith all these objects in view my invention consists, broadly, in the application of an injector to water-closets. v

My invention consists, further, in certain novel features of construction and in combination of parts, which will be first fully described, and afterward specifically pointed out in the appended claims.`

Referring to the accompanying drawings, Figure 1 shows my invention in section. Fig. 2 is a sectionalview of they aspirator to be used in connection with my invention. Fig. 3 is a sectional view of my valve.

I wish to state in connection with the afore- -going figures, particularly Fig. 1, that the pipes and connections are shown in a manner which is best suited to illustrate my invention, but. which in actual practice would be varied to circumstances and arranged. much more compactly witha view to economize space.

Like numerals of reference indicate the same parts throughout the several figures, in

` which- 3 is the flush-tank, provided with the ordinary flush-pipe` 4. i

Connected to the discharge-chamber 2 are the discharge-pipe 5 and the vent-pipe 6,which are connected to the pipe 7.

S is the water-pipe, which is connected to the pipe 9. At a point in said pipe is the valve 10, to which is secured the handle 11, the several parts of which valve will be hereinafter fully described. Below said valve 10 is an aspirator 12, which is connected to the Hush-pipe 4 by means of a siall pipe 13.

To return now to valve 10, it will be seen by referring to Fig. 3 that the same is of simple construction. The valve-stem 14 eX- tends to the exterior and is provided with suitable packing 15 to prevent leakage. The opposite side of the valvechamber is provided with a removable plug 16, which must be removed in order to furnish access to the valve. Said plug is provided with an opening in its inner face, which opening forms a guide for the valve-stem 14. The valve is seated at 17 and arranged so that the pressure of water in pipe 8 tends to hold said valve in a closed position. Pivoted to the exterior of thevalve-chamber is a link 19, to which is pivoted a handle 11, provided with an upthe aspirator 12 is coupled to pipe 8, the bore of said aspirator decreasing from both ends toward the center, at which point this bore is smallest. Directly opposite the central point and atright angles to the bore of theaspirator is an opening 20, in front of which is coupled a valve member 2l, within which are avvalve 22 and an airchamber 23. Behind said valve is a small bore 24, which opens into pipe 13. Said valve is arranged so as to exclude any passage of air or water from the aspirator into pipe 13, but allows a free passage of air from-the opposite direction.

25 is the bowl-cover, which is connected to handle 11 by a suitable connecting-rod 26.

I also provide a small opening or openings 27 between the top of the bowl and the seat IOO 28 for a purpose which will be hereinafter fully described.

Having thus fully sety forth the several partsf of my invention, its operation is as follows: When in operation, the cover is raised, whichV raises the handle Il, thus opening the valve l0. This allows the water in pipe 8 to pass through pipe 9, valve l0, and aspirator 12, this causing a partial vacuum within airchamber 23 in valve member 2l, and sucks the vitiated air from the bowl I up into the iiushpipe 3, through pipe 13, into the air-chamber 23, where it is carried out into pipe 8 and down into vent-pipe 6, and thence to the discharge-pipe 5. rlhe opening or openings 27 between the top of the bowl and the seat 28 allow fresh airto be taken into the bowl to replace the vitiated air which is carried oif, thus causing a free current of air through the bowl as long as the aspirator is in operation. When the bowl is iushed and the seat low-` ered, the valve 10 is closed, which shuts off the supply of water through the aspirator, there being no further need for the same. I construct the pipe 9 so that after the valve l0 is closed the water in the pipe will form a trap at the bottom thereof, so as to prevent any vitiated or foul air from rising in said pipe 9 from the vent or discharge pipe.

I do not wish to' be understood as limiting myself to this specific construction, as the Asame may be varied in many ways and still fall within the limit and scope of my inven.

tion. I wish, furthermore, to state that the valve 10 may be operated manually, if desired, although I prefer to operate the saine automatically, as described.

My invention may also be applied to urinals as well as water-closet bowls, as I have found the same to be particularly useful in connection therewith, and I therefore do not wish to be understood as limiting its application to water-closet bowls.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The combination with a watercloset bowl ofy a flush-pipe an aspirator connected thereto, a water-pipe carrying said aspirator, avalve in said water-pipe, a seat for said bowl, a cover for said seat, connecting means between said seat and said valve; and openings between said seat and bowl,substantially as described.

2. The combination with a water closet bowl of a flush-pipe, an aspirator connected thereto, aV water-pipe carrying said aspirator, a seat for said bowl, openings between said bowl and said seat, a cover for said seat adapted to operate said aspirator, substantially as described.

3. The combination with a water closet bowl of a Hush-pipe, an aspirator connected thereto, a seat, and a cover for said i bowl adapted to operate the aspirator, land means for allowing a draft of air to pass through said bowl, when the same is in use, substantially as described.

4. The combination with a water -closet bowl, of a flush-pipe, a water-pipe, an aspirator connecting said flush-pipe and water-pipe, a valve in said water-pipe, a seat for said bowl, a cover for said seat, connecting means between said seat and said valve, and openings between said seat and bowl.

5. The combination with a water closet bowl, of a hush-pipe, a water-pipe, an aspirator connecting said flush-pipe and said waterpipe, a valve in said water-pipe, a cover for said bowl, connecting means between said cover and said valve and a valve in said aspi rator, arranged whereby the water from said water-pipe is prevented from entering said flush-pipe from the aspirator.

In testimony whereof I aflix my signature in presence of two witnesses.

REVERDY CLEMENT DE LA HUNT.
